LOCOMOTIVE HEAD-LIGHT.

ISPECIFICU-YlIOIltT forming part of Letters Patent No. 267,613, dated November 14, 1882.

Application tiled September 14, 1882. (Model.)v

To all whom it may concern:

Be it known that I, FRANK H. TALBOT, of Rochester, in the county of Monroe and State of New York, have invented a new and useful lmprovement in Locomotive Head-Lights, of which the following is a full, clear, and exact description.

This invention relates to locomotive headlights in which the lamp, in addition to its function proper of showing a front light, is caused to also exhibit side lights for certain indicating purposes.

The invention consistsin a certain arrangement and construction of transparencies, and the frames which carry them for indicating at the sides ofthe head-light by the direct rays of the lamp the number of the train, the num-ber of the section of the train, and the number of the locomotive drawingit, or otherlikeinformation useful or necessary in the running ofa railroad, each of said transparencies being separate, with provision for the removal of them or certain of them as required.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar letters of reference indicate corresponding parts in all the ligures.

Figure 1 represents a side view of a locomotive head-light, with its door removed and having my invention applied. Fig. 2is ahorizontal section of the same on the line 00 a: in Fig. l. Fig. 3 is a view in perspective of one of the fram es which hold certain ofthe transparencies, and Fig. 4 is a horizontal section of another of said frames.

A indicates the case of the lamp or headlight, and B the burner. C is its oil-pot, and D the retlector. Arranged in the sides of the case in front of the reector are a series of transparencies, which by their arrangement. receive the strongest possible light without interfering with the light upon the track ahead, the same being illuminated by the direct rays of the burner. The upper one, E,ofthese transparencies on each sideindicates the number of the engine. As this transparency does not require to be changed, it may be an ordinary darkened glass, with the number of the engine in transparent iigures thereon. Said transparency is set in a frame, b, which may be riveted to the inside of the case A and be constructed to receive the transparency within it from the outside, and which has combined with it an outer retaining frame, c, secured to the frame b by screws or otherwise. A

F and G are other transparencies, also arranged on each side ofthe case in front of the reflector and below the transparency E, or otherwise arranged in relation to each other, as preferred, but being illuminated in like manner by the direct rays of the burner. These transparencies F and G are each contained within a double frame-that is to say, an inner frame, d, which contains a glass, e, and an outer frame, f, which acts as a retainer and serves to hold within it in front of the glass a stencilplate,- g, that may either be a single plate, as shown in Fig. l, or be made up in sections, as shown in Fig. 2, to facilitate changes ofthe indication to be expressed. The transparency F indicates the particular section of a train running on a certain train-number, and the transparency G the number of the train. One end, h, of each outer frame, f, should be made to open and be secured when closed by a springclasp, t, or otherwise, to facilitate removal and changing of the stencils, the glasses c preventing the ingress of air or draft both during such removal and when the stencils are in place. These transparencies F G may, if desired, be used in connection with other means for indieating the number of the locomotive than that which has here been described; but the transparency here shown for the purposeis preferred, as it receives the direct rays of the burner, and can therefore be seen at a greater distance.

My improved locomotive head-light will be found exceedingly serviceable, as all railroad companies run their trains by number in order to distinguish them, and the lamp or head-light here described will show at all times what train is passing,it showing the number of the train, also the particular section, should there be more than one train running cn the same number, and the number ofthe locomotive drawing the train. This will enable train-dispatchers and employs in general on a railroad to see what train is passing. y ,-I,

Having thus described my invention, I claimas new and desireto secure by Letters Patentl. In u locomotive head-light, the combinintion, with its burner B, reflector D, and case A, of the advance side transparencies, F G, for indicating the train-section and number of the train, suid translimrcncics being composed of removable stencil-plates and fixed glasses, essentially as and for the purposes herein set forth.

2. In combination with the case A, the inner and outer frames, df, the one of which is made ro to open, the glass e, sind the stencillplate g of thetransparenciesFG,essentially asdescrihcd.
